Well, everyone who would buy it at $20 has already bought it by now and everyone who would buy it at $10 and/or would buy it once it ended up on Steam has bought it by now.

I figured they would go down to $5 at some point once they saturated their sales at the $10 price point so I waited. That, and I played the demo and was just kind of 'eh' on it, but maybe if I muddle through it it will get better and if not at $5 I can live with 'eh'.
